Title: Apparatus for cleaning hair brushes
IPC: A46B17/06
Filed: 1951-07-02
Abstract: 699,876. Brush-cleaning apparatus. THOMAS, S. A. May 29, 1952 [July 2, 1951], No. 15606/51. Class 19. A device for cleaning and disinfecting hair brushes comprises a casing 1 provided with an aperture 11 through which the head of the brush 12 is inserted. A rotatable shaft 13 having a handle 14 bears three combs 18 and a brush 19. Upon rotation the combs, the teeth of which are staggered, sweep through the whole of the brush being cleaned, while the brush 19 removes surface hairs. The hairs are removed from the combs 18 and brush 19 by means of a fixed brush 22, and the combs then pass through a further brush 21 which is immersed in a bath 20 of disinfectant. A holder for the brush being cleaned comprises two slides 23 mounted on springs 25. The effective width of the slides is limited by strips 26 and each is provided with fingers 29 extending over the opposite slide to ensure the slides do not collapse.

Title: Improvements in or relating to variable speed power transmission mechanism
IPC: F16H61/664
Filed: 1935-05-29
Abstract: 443,472. Variable-speed friction gearing. HAYES, F. A., Red Hill Road, Middletown, New Jersey, U.S.A. May 29, 1935, No. 15633. [Class 80 (ii)] In addition to being responsive to driving, driven or reaction torque, the end-loading means, in a toric-disc gear is also responsive to the angularity of, and, if desired, also to the contact radius of the rollers 10. In Figs. 1 and 3, an axial projection 29 of the driving shaft 1, applies torque to the variable loading-points 27 of beams 31, connecting the driving disc 6 with the torquering 13 of a cam-and-ball torque-responsive device 14. The relative proportions of torque received by the torque-ring 13 and disc 6 and so the end-loading, is determined by the position of the loading-point 27, which latter is moved along the beam 31 by the tilting of the rollers 10, acting through a link 21 and a ball-race 23, the loading-point itself comprising a pair of balls 28 carried by the ball-race. The beam may be duplicated so as to act also in reverse. In a modification, (Fig. 5, not shown), the roller-carrier acts on the ball-race 23 through a cam, so shaped as to render the end-loading means also responsive to the contact-radius of the rollers. To adapt the device shown in Fig. 1 for use with planetary instead of non-planetary rollers, a fixed guide 25 is carried by the planetating element. In a non-precessional form, (Fig. 7, not shown), the loading-points are carried by a member connected to a controlling handle which directly tilts the rollers. In the duplex gear shown in Fig. 8, tilting of the rear rollers 95 is directly transmitted to movable loading points 88, by a cam-slotted flange 96 and a sliding key 92. In a modification, (Fig. 6, not shown), the loading-points are moved by the front rollers, in which case the longitudinal movement of a transmitting member, arranged in the centre of the shaft, has to be reversed by a simple lever. British Specifications 344,061, 344,062, and 392,589, and U.S.A. Specification 1,919,218 are referred to.

Patent GB-636348-A (GB)
Title: Production of synthetic polymers
IPC: C08G69/28
Filed: 1947-06-18
Abstract: Linear polyamides are produced by reacting a di-ester of oxalic acid with a substantially equimolecular proportion of a diprimary diamine without the application of heat.  The reaction may be carried out by mixing solutions of the reagents, e.g. in alcohols, ethers, or hydrocarbons with or without catalysts such as phosphoric or benzoic acid at room temperature, whereupon the polymer precipitates. Specified are di-esters: methyl, ethyl, phenyl, and cresyl oxalates; amines: one or more of tetra-, hexa-, or decamethylene diamines, others of formula NH2(CH2)nNH2, where n is at least 3, 2,21-diaminodiethyl-ether and thioether, bis-(g -aminopropyl) - ethylamine, p - xylylene diamine, 2,5-diamino hexane. 2,21-diamino-diethyl sulphone, and 4-hydroxy-heptamethylene diamine. The solvent is selected to control the maximum temperature of the reaction or external cooling to 50 DEG  C. or 25 DEG  C. may be employed.  The reaction may also be performed in the presence of non-solvents or in the absence of solvents.  In examples: (1) equimolecular proportions of ethanol solutions of ethyl oxalate and decamethylene diamine are mixed at room temperature and the precipitated polymer is dried under vacuum.  It is partially soluble in m-cresol, formic acid, formamide, and aqueous solutions of lithium bromide and zinc chloride; (2) the process of (1) is followed but with hexamethylene diamine and ethyl oxalate.  Filaments may be produced by melt spinning the products and sulphonamide, phenolic, urea, or thiourea plasticizers may be added to the melt. Filaments may also be spun from solutions in formic or acetic acid, cyanohydrins, or phenolic solvents, e.g. phenol or cresol. The polymers may be mixed with cellulose acetate, acetobutyrate, butyrate, and acetostearate, ethyl cellulose, oxyethyl cellulose, oxyethyl cellulose acetate, benzyl cellulose and other cellulose derivatives, plasticizers or softening agents, dyestuffs, and pigments.

Title: Improvements in or relating to casting cells for the polymerisation of unsaturated organic compounds
Inventor: PAKENHAM GEORGE ROBIN MONTAGU
IPC: B29C39/00
Filed: 1951-07-09
Abstract: 708,076. Casting-cells for polymerising organic compounds. IMPERIAL CHEMICAL INDUSTRIES, Ltd. June 23, 1952 [July 9, 1951], No. 16199/51. Class 87 (2) Relates to the production of flat sheets of thermoplastic polymeric material by the polymerisation of an organic compound containing the group CH2=C<; in which each side wall comprises a metal front member having a flat casting surface and a metal supporting member, the supporting member being of more rigid construction than the front member and attached thereto by a plurality of attachments which maintain the front member in a fixed position relative to the supporting member, and each of which is capable of fine adjustment so that very small changes can be made in the relative positions of any portion of the casting surface and the supporting member. In the arrangement shown in Fig. 2 the flatness of the plate 21 is adjustable by bolts, e.g, 26, 27, distributed over its area. Each bolt is threaded through a sleeve 34 fixed in the supporting member 20 and is also threaded into a block, e.g. 23, fixed to the plate 21, and the number of threads per inch in the sleeves is slightly different from the number in the blocks. This thread difference gives a differential action so that a large rotational movement of the bolt results in a small alteration in the distance between the members 20, 21 and fine adjustment is then possible; and this effect is enhanced by the nature of the supporting member 20 which, though rigid as compared with the plate 21, is sufficiently flexible to allow slight movement in the region of a bolt. In Fig. 3, in which one bolt 44 only is shown, a collar 45 is used with an external thread 46 of different pitch to the internal thread 47. The bolt is locked to the plate 42 by a nut 48 and is threaded through the collar 45, and the collar is threaded in a sleeve 50 which is locked to. the supporting member 40 by a nut 49. Rotation of the collar 45 then results in relative movement between the plate 42 and the supporting member 40. Heat control can be achieved by placing the cell in an oven, but the casting surface, e.g. the plate 42, is preferably fitted with a jacket for circulating a heating or a cooling medium, e.g. by the addition of a plate 41. The casting surface may be of highly polished metal, preferably stainless steel, or a film or organic polymeric material may be applied to a metal surface, e.g. by spraying, or a metal surface may be plated with a thin layer of a suitable metal. A sheet of highly polished material, e.g. glass, may also be secured, e.g. by vacuum, to the front member. Suitable compounds for casting into sheets by means of the apparatus are esters of a substituted acrylic acids, e.g. methyl, isopropyl and cyclohexyl methacrylate and styrene. Specification 450,305, [Group IV], is referred to.
